OBJECTIVES

To introduce new orange varieties (Early, mid and late) to expand the availability period of Citrus.

Promotion of seedless orange varieties. Executing research for the improvement

of yield & quality of oranges through suitable cultural and orchard management techniques (irrigation, plant protection, nutrition, pruning etc.

Identification of research on the diseases & pests present in Citrus orchards and to find out the effective control measures.

To conduct studies for the reduction of post harvest losses in Citrus

Research on nursery management.Production of nursery plants of

different citrus fruits varieties. Advisory service to the growers

Rootstock Evaluation

• A broad based rootstock evaluation programme for improving the yield and fruit quality is under way. Carrizo citrange, Troyer citrange, volkamirana, mithi, kharna khata and gadha dahi have been evaluated for salustiana sweet orange. Plant growth and better fruit quality have been attained in citranges

Development of Double Grafting Technique

• Through using graft wood of quality improving citrus species i.e. Sweet lime, C-35 citrange, Carrizo citrange better internal quality character have been achieved

Nutritional Studies including micronutrients

• NPK at 1000 -500 – 500 gm/plant + FYM at 60 kg/plant recommended for better yield.

• Attained increase in yield as 15.19% with the application of B at 60 ppm.

Water saving through Furrow Irrigation

• Furrow Irrigation resulted in substantial saving of irrigation water up to 60% as compared to Flood irrigation.

• Plants remained un-affected from soil born fungal diseases in furrow irrigation.

Pressurized irrigation system in citrus orchards.

• Drip • Sprinkler (Turbo-gyronet) • Sprinkler- gyronet

Sprinkler (Turbo-gyronet) Sprinkler- gyronet Drip

Findings:

Better yield per plant i.e. 145 kg were abstained in drip system where as Turbo gyronet 137.12 kg/plant proved the next better method.

MEASUREMENT OF THE WATER QUANTITY BY USING FLUM METER

Disease Studies • Detected Causes of Citrus Decline Abnormal

Temperature surge during summer and soil born fungus species are the main causes

• Control of Citrus Scab disease through topspin-M and Copper Oxychloride with respective doses of 1.5 gm and 2.5 gm/lit. have been achieved.

• Citrus Greening through Iodine testing method identification of citrus greening was done in sectional orchard on Star Ruby Grapefruit and Hamlin sweet orange

• Fungicides and Antibiotic were tested for their efficacy where streptomycin spray at 1 gm/lit. proved effective on grapefruit which is very susceptible to Citrus Canker

Control of Citrus Canker

Insect Pest Survey in Sargodha Area

• Citrus Psylla 49% • Mealy bug 44 %• Leaf miner 45 %• Fruit Fly 70 %• Lemon butter fly 48 %• Thrips 40 %• Mites 20 %• Scales 25 %

• Prevalence of fruitfully was more as compared to other pests. Next to fruit fly Citrus Psylla was found as problematic pests.

CITRUS DECLINE• Training Programmes in different Tehsils

through farmers days 8

• Union Council Level 38

– The problem of Citrus Decline reverted to a reasonable extent

Completion and Compilation of Survey Report on size reduction and quality degradation in kinnow

mandarin

COPMLETED

• Exhibition/Seminars 3

• Varietal Registration– Kinnow – Salustiana Orange– Feutrell’s early– Shamber Grapfruit

• Geographical indication of kinnow

– In collaboration with Kinnow Growers Association the development of document for bringing Sargodha kinnow under geographical indication submitted.

• Indexation work for the selection of less seedy kinnow completed

• Registration of Nursery
